the shaft 53 but slidable thereon by means of the operating levers 56, 56*, 57 and 57 respectively, which may lead to a position adjacent the drivers seat if the device is used as a. sullry plow, or may lead to the operators position if tractor drawn. In or-. der to raise or lower each wheel, a lug. 58 projects from the upstanding portion 47 of the axle through the back of'the guide channel 48 to .which is attached a chain or cable 59 passing downwardly over a pulley or sheave 6O fixed to themain frame and upward to the winding drum 55. For retracting either set of plows from cooperation with the ground, a chain or'cable 61 passes over each winding drum 54 to the pulley 62 and down to the cross pieces 19 and 20 to which the lower end of the cable may be attached. Retract-ile springs 63 hold the operating levers 56, 56 57 and 57 no'rmally in a position in which the complementary clutch members do not cooperate. any cooperating clutch memberengages its winding drum to rotatethe same, the drum may be heljd'in a partially or fully wound position by means of spring pressed pawls' 65,65, 65 and 65 cooperating with the ratchets 66 fixed on eachwinding drum. Releasing rods 67, 67 67 and 67 also lead ing to the drivers or operators position are provided for releasing the pawl in order that any one'of the winding drums may be unwound as much as desired.

In operation, to adjust the plow in order that one set or gang of plows, for instance the right hand set, may be in working position, the handle 45 may be moved to 000p crate with thenotch indicated when the side wheels 37 and 38 'will be swung about the pivot 40 yet remain parallel with each other. If the machine is being drawn during this operation, the wheel 37 will be moved ahead of thewheel 38 to the position shown, and at the same time the main frame becoming angularly disposed will be swung about the single point of attachment 22 so that the drawing force, single point of attachment and operative plows w ll be in alinement and parallel wtih the side wheels. Thus a singleshifting means is providing for the lVith the left wheel 37 disposed ahead of the wheel These lVhen Y .to raising the main frame and operative plow, the sliding lever 57 or 57 -may, be moved into cooperation with whichever winding drum 55-is desired to be operated when the cable 60 will be wound and wheel adjusted relative to the mainframe the desired amount, after which the operating lever 57 or 51'' may be released to disengage the cooperating clutch members. At the end ate with the other gang, the set of plows 12 and 13 may be elevated to an inoperative of the furrow should itbe desired to operposition by operation of a lever '56 to wind 1 the appropriate drum 54 the desired amount. To lower eithersetof plows .thepawl lever 67 or 67 maybe operated to release thev pawl or ratchet and allowthe desired drum 54 to unwind. In the same wayoperating the rods 67 or 67 releases the pawl and ratchet of the desired winding drum 55. It will be seen that if the machine is 111 motlon,

operating the handle 45 is in effect moving l the main frame, fore-frame, and both wheels about the single point of attachment. 22 as a pivot.

Among the advantages of my device may be enumerated the ease of' alining the. operating plows and drawing force by means'of the single adjusting handle 45 which not only alines the'drawing force and opera-' tive plows but at the samev time moves the land wheel ahead. of the other for a better distribution of forces within the plow frame and a better guiding of the machine. hen the sets or gangs are disposed at a fixed horizontal oblique angle to eachother, an advantageous lateral space economy results since the inoperative plow is then disposed back of the wheel on the land side in an out of the way position instead of being placed above or at the side of the working plow. The ease of adjustmentof the depth of the furrow by adjusting the height of each Ill) wheel independently of the other. which ad I same adjusting shaft 53, driven from one of a the side wheels is a further advantage. lVith the plows arranged at a fixed horizontal angle with oneanother, a rigid and substantial frame results for the two-way plows. One of the most noteworthy features of my invention is the single point ofattachment 2 f r th draw g are which s e inite y X d "relative-t ach ple t yet. the; he

and main ,frame are. movab-leto have the drawing force 'alined with the line of. draft 1 of the operating plow which insuresa cer} tainty of alinement.
